Stop inhaling toxic gases and keep volatile organic compounds out of your lungs. This activated carbon mask conforms to the EN 149:2001 standard. It has an FFP2 rating, which means that it’ll keep out 94% of PM 2.5.

This mask should last for 3 to 4 weeks with around 3 hours of use per day in Delhi.

What is activated carbon/ charcoal? Activated charcoal and regular charcoal are almost identical. Activated charcoal is created by heating it with a gas that causes the charcoal to expand and create a porous surface that helps trap toxins. This activated charcoal works by chemically binding other substances to its surface and can absorb thousands of time its own weight. It has an incredibly large surface area due to its pores. A cubic inch of charcoal has the surface area equivalent to a 150,000 square foot field.

 Do masks actually work?

Lots of smart, skeptical people question this. Fortunately, scientists have done the hard work for us! Here’s what their data says for the three most common questions we hear at Smart Air.


Do masks capture the really small particles?

Different mask effectiveness

This is the easiest question to answer. Researchers at the University of Edinburgh tested different masks by running diesel exhaust through them and measuring how many small 0.007 micron particles the masks blocked.

Bottom line: Test data shows masks capture even the really tiny particles.


Do masks work when you wear them?

This question is tougher to answer. You need a $10,000 machine like this one to test it. Our N99 mask was fit tested in a lab in Mumbai, and the results showed the mask was blocking 99.3% percent of particles. Our tests from Beijing and published scientific studies found similar results. Bottom line: masks work well even while people are wearing them.

How long do masks last?

How long do air pollution masks lastThomas tested a new N99 mask and a mask he had worn for 11 days in Beijing. The new mask blocked 99%; the old mask blocked 98%. This data suggests they last at least 11 days. Not bad! After 2-3 weeks, you’ll probably want to throw the mask away anyway because it gets gross!

    Great mask. I’ve used it under helmet while riding bike in Bangalore traffic. Didn’t smell smoke at all!
    Highly recommended.
